I\'ve created a project with a Core Data model in it. The application looks for the model file (.momd) and runs just fine.

This method will get your bundle from any target. However, for each target you add, you have to manually add the plist bundle identifier to the identifiers array, because there is no way to get it programmatically. The advantage is that you can use the same code for testing or running the application.

+(NSBundle*) getBundle 
{
    NSBundle *bundle = nil;

    // try your manually set bundles
    NSArray *identifiers = [NSArray arrayWithObjects: @"com.your.application",
                                                      @"com.your.test",
                                                      nil];
    for(NSString *bundleId in identifiers) {
        bundle = [NSBundle bundleWithIdentifier:bundleId];
        if (bundle!=nil) break;
    }

    // try the main bundle
    if (bundle==nil) bundle = [NSBundle mainBundle];

    // abort
    assert(bundle!=nil && "Missing bundle. Check the Bundle identifier on 
           the plist of this target vs the identifiers array in this class.");

    return bundle;
}
